Cross-hatch Pattern Adjustment Example
Although image size is determined using zoom, if the horizontal lines in between do not connect,
projection angle is not going to be the same. Please readjust the angle until the lines connect.
Example Pattern A: The left side screen is stretched from top to bottom. Or, the right side
screen’s top part stretched, while the bottom part contracted.
Example Pattern B: The left side screen’s top part stretched, and bottom part contracted. Or the
right side screen’s top part contracted, and bottom part stretched.
Even though the screen size matched horizontally, the hatch lines in between do not match.
This is because the left side or the right side projector, or perhaps both projectors’ vertical angle
do not match. And also please check and correct trapezoidal distortion in the vertical direction
by comparing the screen frame with the cross-hatch pattern.
